It's been a while since I posted here, but I would really like some advice from you guys.
I have a pair of Head S90's which I've had for about 4 years. I've had a custom insole fitted to them when I bought them, but other than that there was no fitting performed. I've been pretty happy with them but recently (and especially after a 5 day trip to Snowmass) I feel that the boots have been wearing out. The reason I'm saying this is because I need to buckle them as tight as I can to get enough control when carving. I've also noticed some new pressure points in the front of my foot which, I suspect, are the result of buckling too tight.
I've been considering two options: getting new boots altogether or getting a new (fitted) liner/insoles for the current ones I have.
What I'd like to understand is this:
1. given that the boots are a 2009 model, is it even possible to get a new liner for them?
2. Would a new liner restore performance?
3. The S90 have a flex index of 90-100. I mostly like to carve groomed steep blacks and I've recently gotten to the point of being comfortable in big bumps/glades and some powder. My skis are a pair of Dynastar Contact 4x4's. Given this I'm trying to understand whether the S90 is too soft and if I'd benefit from a boot with a stiffer boot.
Thanks in advance
